Python中类的继承代码实例

运行效果：

[root@localhost hhl]# python pyclass.py   
Member init:Tom  
Student init:Tom  
Member init:Mrs.Huang  
Teacher init:Mrs.Huang  
Name:Tom,Age:20 Marks:80  
Name:Mrs.Huang,Age:30 Salary:50000 

我们同样编写同样效果的C++例子：

//filename: class.cpp  
#include <string.h>  
#include <iostream>  
using namespace std;  
 
class Member  
{  
public:  
    Member(char *n, int a);  
    void tell();  
private:  
    char name[10];  
    int age;  
};  
 
Member::Member(char *n, int a)  
{  
    memcpy(name, n, sizeof(name));  
    age = a;  
    cout<<"Member init:"<<name<<endl;  
}  
 
void Member::tell()  
{  
    cout<<"Name:"<<name<<","<<"Age:"<<age<<",";  
}  
 
class Student:public Member  
{  
public:  
    Student(char *n, int a, int m);  
    void tell_s();  
private:  
    int marks;  
};  
 
Student::Student(char *n, int a, int m):Member(n, a)  
{  
    marks = m;  
    cout<<"Student init:"<<n<<endl;  
}  
 
void Student::tell_s()  
{  
    Member::tell();  
    cout<<"Marks:"<<marks<<endl;  
}  
 
class Teacher:public Member  
{  
public:  
    Teacher(char *n, int a, int s);  
    void tell_t();  
private:  
    int salary;  
};  
 
Teacher::Teacher(char *n, int a, int s):Member(n, a)  
{  
    salary = s;  
    cout<<"Teacher init:"<<n<<endl;  
}  
 
void Teacher::tell_t()  
{  
    Member::tell();  
    cout<<"Salary:"<<salary<<endl;
